Switchable smart pdlc film is a combination of two electrically conductive films, filled with liquid crystals and polymer. LC particles, by electrical connections, stand in one direction to let the light pass through and create transparency. As the current is off the particles are scattered in various directions; consequently they partially impede the pass of the light and cause the opacity. You may know more details from pdlc film wiki.
